TECHNOLOGY OF MANUFACTURING UNIVERSAL CLUTCH FOR
WITHOUT WELFARE, WITHOUT CUT-OFF, WITHOUT-FLANGE CONNECTION OF PIPE CUTS
IN HIGH PRESSURE PIPES

Manufacturing technology of a universal coupling for a weldless, threadless, flangeless connection of pipe sections in pipelines with a nominal working pressure of 150 or more atmospheres. The implementation period is 1.5-3 months.

I have developed a technology for manufacturing universal couplings made of various materials for the WITHOUT WELDING connection of pipe sections (metal and plastic) of various diameters and purposes. This connection method differs from the well-known Georg Fisher technology in that pipe sections are not fixed by compressing sealing material around the pipe, which does not ensure the strength of the connection at high pressure and when pipes are in a vertical plane, but by mechanical fixation of pipe sections in the coupling.

The strength of my joint is comparable to the strength of a solid pipe with a nominal operating pressure of up to 150 atm . In addition, the method of the proposed connection, carried out manually, eliminates significant physical effort during installation. The use of a new coupling excludes threading and welding flanges. Connection and carried out at different angles.

The value of the coupling lies in its universal use, but above all in its use in harsh working conditions: in mines with gassed air and increased explosive hazards, in factories, etc.

Benefits:

1) low cost method;
2) ease of installation (two pieces of pipe are inserted into the coupling on both sides and parts of the coupling are rotated relative to each other);
3) welding and other labor-intensive operations are excluded;
4) cheapness of the coupling itself;
5) the ability to connect pipes of different materials and different diameters;
6) when repairing pipes, damage to the interior of the building is excluded;
7) small contributions to production and the absence of competitors in the market;
8) increased demand.
